[0001] This utility model belongs to the field of precast pile bending resistance testing technology, and relates to a precast pile bending resistance testing positioning device. Background Technology

[0002] For example, Chinese patent literature discloses a hollow square pile bending resistance test device [202211081417.6], which includes a set of symmetrically distributed pushing components. The top of the pushing components is provided with a support plate, the bottom of the pushing components is provided with a pressure sensor, and a push rod is provided between the tops of the two pushing components. The bottom end of the push rod is connected to a pressure plate for performing a compression test on the pile body.

[0003] The drawback of the above technical solution is that when the pile is placed at the test position, it is not easy to move axially, which makes it impossible to achieve bending resistance test at the center position or multiple points of the pile. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a precast pile bending resistance detection and positioning device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

Detailed Implementation

[0025] Example 1

[0026] Please see Figures 1 to 3 This is a schematic diagram of a precast pile bending resistance testing and positioning device provided by this utility model. The precast pile bending resistance testing and positioning device includes: a support base 10; on the support base 10, support sliders 20, abutment components 30, and pressing components 40 are arranged sequentially from both ends inward. It can be imagined that this precast pile bending resistance testing and positioning device also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0027] In this embodiment, the support base 10 is set on the ground or a test platform. The support base 10 is elongated and serves as an installation carrier. A guide rail structure is provided at the upper end of the support base 10.

[0028] In this embodiment, precast piles are generally transported by forklift or gantry crane. Two support sliders 20 are provided on the support base 10 and slidably arranged along the length of the support base 10. A support platform 21 is provided at the upper end of the support sliders 20. The bottom surface of the support platform 21 is used to initially receive the precast pile, and a baffle 22 is provided on one side of the support platform 21 along its width direction. The baffle 22 is used to laterally limit the precast pile and increase the flatness of the received precast pile. The upper surface of the support platform 21 is inclined, and the inclination direction of the inclined surface is downward along the width direction towards the baffle 22, increasing the stability of the precast pile on the support platform 21. Increasing the inclination angle of the support platform 21 can also be used for positioning and placing circular piles.

[0029] The abutment assembly 30 includes two abutment sliders 31 slidably mounted on the support base 10. The two abutment sliders 31 are positioned between two support sliders 20. When the precast pile is transported to the support slider 20, the relative position of the abutment sliders 31 and the precast pile is adjusted, for example, symmetrically positioned around the midpoint of the precast pile. A vertically lifting abutment block 32 is provided at the upper end of the abutment sliders 31. The abutment block 32 is connected to a hydraulic actuator for lifting drive. The abutment block 32 abuts against the bottom of the precast pile, simultaneously forcing the precast pile to detach from the support platform 21. The abutment block 32 serves as a support structure during the bending resistance test of the precast pile. The secondary abutment facilitates adjustment of the precast pile's state, increasing test accuracy. A recessed limiting groove 33 is provided at the upper end of the abutment block 32, ensuring that the precast pile cannot detach from the abutment block 32. The bottom of the limiting groove 33 is flat, which corresponds to the positioning when the precast pile body has a rectangular outline. In addition, a recessed V-shaped notch 34 is provided in the middle of the limiting groove 33, which corresponds to the positioning when the precast pile body has a circular outline, thus preventing the precast pile body from shifting.

[0030] The pressing assembly 40 includes a pressing base 41 slidably disposed on the support base 10. The pressing base 41 is positioned between two abutting sliders 31. In this embodiment, the pressing base 41 is positioned at the midpoint of the support base 10. It is conceivable that when the same precast pile has multiple detection points, the position of the abutting sliders 31 can be adjusted. Optimally, a connecting rod can be provided between the abutting sliders 31 and the pressing base 41 to achieve synchronous sliding on the support base 10, thereby improving adjustment efficiency.

[0031] A horizontally recessed clearance notch 42 is provided on the pressing base 41, with its opening facing away from the baffle 22, for the precast pile to be embedded. A rotating platform 44 is horizontally rotatably connected to the upper end of the pressing base 41, and a pressing block 43 is located at the lower end of the rotating platform 44. The rotating platform 44 is connected to a rotary motor, which can drive the rotating platform 44 to move the pressing block 43 above the clearance notch 42. A driver 45 is provided on the rotating platform 44 to drive the pressing block 43. The driver 45 is hydraulically driven, and the driver 45 drives the pressing block 43 to extend into the clearance notch 42 and press down on the upper end of the precast pile to achieve bending resistance testing, and finally obtain the test value. It is conceivable that when the precast pile is initially transported, the pressing head can be rotated to the outside of the clearance notch 42 in advance, which can enable the precast pile to be vertically hoisted and avoid collision problems during horizontal transport.

[0032] In this embodiment, an elastic abutment frame 50 is provided on the outer circumferential side of the lower pressure block 43. The elastic abutment frame 50 descends with the lower pressure block 43, pre-contacting the precast pile body, thus providing a contact buffer effect and increasing the contact area with the precast pile body. This ensures the stability of the force applied by the lower pressure block 43 to the precast pile body, and plays a role in auxiliary positioning. It is conceivable that the force exerted by the elastic abutment frame 50 on the precast pile body is negligible compared to the force exerted by the lower pressure block 43, and will not affect the test results.

[0033] The lower end of the elastic support frame 50 is provided with a support surface 51, which corresponds to the outer wall shape of the precast pile body. The support surface 51 increases the fit between the elastic support frame 50 and the precast pile body. If the precast pile body is rectangular, the support surface 51 is a flat surface; if the precast pile body is circular, the support surface 51 is an arc-shaped concave surface.

[0034] In this embodiment, the positions of the support slider 20, the abutment slider 31, and the pressing base 41 on the support base 10 are all adjusted by a horizontal drive motor or manually. More optimally, the support base 10 is provided with a stop notch 11, and the support slider 20, the abutment slider 31, and the pressing base 41 are all hinged with positioning blocks 12 that can be inserted into the stop notch 11. By rotating the positioning blocks 12 into the stop notch 11, the axial position stability of the support slider 20, the abutment slider 31, and the pressing base 41 is ensured.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
